TORCH.

. Application filed June 6,

7 ing tube also containing a wick that is supplied with alcohol or gasoline from another reservoir. Tn operating a torch of this kind the burner wick is lighted and its flame heats the vapor delivering nozzle and vaporizes the gasoline that is delivered to the latter by its wick causing vapor to be discharged from the nozzle under pressure across and through the flame from the burner thus projecting a concentrated pencil-like flame. In all forms of torches, as heretofore constrhcted, and with which 1am familiar, the vapor delivering nozzle was constituted by the end of a tube containing the wick referred to and continued use of a torch so constructed resulted in so overheating the tube as to frequently char and thereby destroy the wick within the tube requiring the device to be disassembled and a new wick substituted for the destroyed one. My invention provides an improved torch wherein the delivery end of the tube or conduit supplying the gasoline that is to be vaporized is surrounded by a. jacket that provides an annular chamber or space between the jacket and the delivery end portion of the tube through which the alcohol or alcohol vapor passes in a re-entrant fashion to an outlet port some distance back of the delivery end of the tube, said outlet being positioned to project the vapor discharging therefrom in a stream across or through the flame of the burner. This construction results in several important advantages, viz., the acket being interposed between the end portion of the delivery tube and the flame of the burner with an intervening annular space occupied by vapor that is traveling toward the outlet eifectually insulates the end portion of the delivery tube suiiiciently to prevent charring of the wick within said tube no matter how long the torch is used; the jacket provides a retort of relatively large capacity within which is maintained a supply of vapor under 1927. Serial No. 196,930.

pressure, and by properly positioning the I out-let from this retort with respect to the burner, oarticularly as described later, the torch w1 function the same when held in any possible position. So far as I know no torch of this class has heretofore been produced which will function in all possible poslt-ions in which it may be held.

Other features of my invention are hereinafter pointed out.

In the accompanying drawings: F1gure 1 1s a. side elevation of a torch con structed in accordance with my invention.

Figure 2 is ac-ent-ral vertical sectional viewof the torch shown in Fig. 1. p I

Figure 3 is a. section on line 33 of Fig. 1.

. Figure 1 is an enlarged sectional view on line 4 4 of Fig. 2.

My improved torch as herein shown comprises a hollow sheet metal body 1 constructed interiorly, and intermediate its ends, wit-h a partition 2 providing two reservoirs 3 and 4. Within the body 1 is a burner tube 5 whose lower end terminates short of but near the bottom Wall 6 of the body and whose upper end portion extends through and is soldered or brazed to the top wall 8 of the body. The body 1 is, as shown in Fig. 3, of flattened tubular form and near one end of top wall 8 thereis provided a. hole 9 within which is soldered or brazed an exteriorly threaded nipple 10 which projects outwardly beyond the end wall 8. A delivery tube 11 extends through the nipple 10 whose outer end portion is formed with a counterbore 12 providing a shoulder 13 serving as a seat for a fiber washer 14. Against the outer. side of the fiber washer 14 is seated an annular flange 15 provided on the delivery tube 11. An interiorly threaded cap 16 is screwed down on to the nipple 10 and by engagement with the flange 15 clamps the latter tightly against the fiber washer 14, and the latter tightly against the shoulder 13 thereby providing a tight oint past which it is impossible for the contents of the reservoir 4: to leak. At the same time the. delivery tube 11, as will be clear, can be turned on the axis of the nipple 10 to swing its delivery end laterally. That is, the outer portion of the delivery tube 11 is of goose-neck form and its delivery end portion 11" can be swung laterally on the axis of the nipple 10.

The upper end portion of the burner tube 5 extends outside of the end wall 8 and terminates near the delivery end portion 11 V of the delivery tube 11. This burner tube 5 posed With relation to thebody 1 and "the axis of the delivery portion 11 of the deliverytube 11, and its chime 18 occupies a plane that is parallel with the axis 01 the letter, said chime is oblique with relation to the. axis of the burner tube 5 and, therefore, of

elliptical 'form as shown in Fig. 3, the width of said ellipse being the same as the diameter of the tube 5 but with the length of the ellipse greater than said diameter. Therefore, the surface area of the exposed wick at the chime 18 is greater than the cross-sectional area of the tube 5. In other torches, as heretofore constructed, the chime 18'has always been at right angles to the axis of the tube 5 and consequently the area of the exposed wick was the same as the cross-sectional area of the tube 5 and as a result flooding would occur at the chime 15 causing the overflow of burning fuel. By making the chime 18 oblique with relation to the axis of the tube 5 the exposed area of the wick at the delivery end of the tube 5 is greater than the cross sectional area of said tube so that the rate'of combustion for a given size tube 5 is greater than heretofore and sufiiciently great to effectually prevent flooding. By positioning the burner tube 5 obliquely, as shown and described, it will be clear that if the torch is turned from the position shown in Fig. 2 ninety degrees in a left hand or contra clockwise direction the inner end of the burner tube 5 will then be at the top of the reservoir 3 and its liquid contents at the bottom, thus preventing a head-which would force the liquid. down a through the wick 17 faster than it was being consumed at the chime 18. It will also be clear that if the torch is-turned ninety degrees in a clockwise, or right hand, direction from the position shown in Fig. 2, the deliv ery end of the burner tube 5 will be very slightly below, or above the level of the liquid Within the reservoir 3 so that there will then be practically no head to force the liquid through the wick to the delivery end. It will also be clear that it the torch is turned upside down from the position shown in Fig. 2 the inner end of the burner tube 5 will be closely adjacent or above the level of theliquid within reservoir 3 so that inthis position also, there will be no head of liquid to speak of to force the same through the wick to the delivery end of tube 5. It should be clear,

therefore, that however the torch may be po sitioned there is, as a practical matter, no time when there is any substantial head of liquid within reservoir .3 tending to force liquid out through the wick of burner tube 5. fThe laterally extending delivery portion 11 of the delivery tube 11 is provided with an exteriorly threaded flange 19 to receive upon it the interiorly threaded inner end of a retort or jacket in the i'ornn'as herein shown, of a sleeve 20 that is closed at its outer end by an endwall 21. i

In the end of the delivery tube 11 is provided a screen 22 herein shown as a strip of wire gauge or fabric rolled into cylindrical form and pushed into the end ot the tube so that it holds itself in place frictionally.

Nithin the delivery tube 11 there is provided the usual wick23 within whose inner end portion is incorporated a metal. wire 24: for use in threading the wick through the hole of bushinglO when assembling the aside and the cap removed after which the delivery tube is returned to its position op posite the end of burner tube 5. A pair of spring jaws 28 are provided upon the side of body 1 with which chain 27 may be en" gaged when the cap is removed from the burner tube.

\Vhen the torch is in operation the flame from the upper end of the burner tube 5 heats the retort sleeve 20 and warms the upper end of the delivery tube 11'v thereby vaporizing the alcohol or gasoline that is-within the tube 11 and sleeve 20, the fluid passing up through the wick 23 and screen 22 into the retort sleeve 20 where it is thoroughly vaporized. From the forward end of the retortsleeve 20 the vapor passes backwardly through the annular space bctween the nozzle portion 11 of tube 11 and the retort sleeve 20 into arelatively large annular chamber 29 from which it escapes under pressure through the outlet 30 that is directed forwardly across and through the flame from burner tube 5. As will-be seen from Fig. 2 the outlet 30 is positioned above the middle of the outlet end of the burner tube 5 and close to the same. The result is that the flame is so confined bee tween the retort sleeve 20 and the outlet end of burner tube 5 that no matter in what position the torch isheld the outletBO is within the flame fromthe burner tube and, therefore, the torch operates the same no matter what position it occupies. This is due also in part to the fact that the stream of vapor issuing under pressure from the outlet 30 creates a suction or draft which holds the flame of the burner tube around said stream whatever be the position of the torch and I find that this efiect is best secured by positioning the outlet 30 close to and opposite the middle of the outlet end of the burner tube.

The reservoir 3 is provided with a filler hole 31 normally closed by a removable cover 82. Reservoir l is filled through the nipple after removing tube 11 and cap 16.

What I claim is: V
